Can you play Kingdom Hearts II in your browser?
Yes, with a disc image you own. Play! reports Kingdom Hearts II as fully playable, and Play! runs in a browser. Use our browser emulator. Keep in mind that the tracker covers Play! on every platform, and its browser version is described by the project as an experiment, so results in a browser can be worse than on a desktop.

Which Kingdom Hearts II disc should you use?
The Play! tracker lists three discs. The NTSC-U disc (SLUS-21005) is Playable, tested on September 10, 2025, with the note that pre-rendered videos run below full speed. The NTSC-J Final Mix disc (SLPM-66675) is also Playable, tested on September 22, 2025, with the same video complaint: the pre-rendered videos crawl compared with the real-time cutscenes and gameplay.
The PAL disc (SLES-54235) is marked In-game, tested on August 30, 2023. Reported problems include skipped starts of voice clips, Roxas sometimes muted in battle, a brief lens flare through walls in Twilight Town, and very slow videos. That report was made on Windows 11. For a browser, the NTSC-U or Final Mix discs have the better tracker status, though results in a browser may differ.

How to play Kingdom Hearts II in your browser
- Make a disc image (for example an ISO) from your own copy of Kingdom Hearts II. We do not provide game files.
- If you have a choice of versions, the NTSC-U release (SLUS-21005) has the best reported result.
- Open our browser emulator in a recent version of Chrome or Firefox.
- Pick your disc image. Play!.js reads the file locally inside your browser (as its source code shows); it is not uploaded.
Kingdom Hearts II controls in the browser emulator
Play!.js is played with the keyboard. Its default layout maps the PS2 controller like this; the browser build sets up no gamepad bindings by default. Click the game screen once before you start: the emulator listens for key presses on its game screen, so keys only register while it has focus.
| PS2 controller | Keyboard |
|---|---|
| D-pad | Arrow keys |
| Left analog stick | T / F / G / H (up / left / down / right) |
| Right analog stick | I / J / K / L |
| Cross ✕ | Z |
| Circle ○ | X |
| Square □ | A |
| Triangle △ | S |
| L1 / L2 / L3 | 1 / 2 / 3 |
| R1 / R2 / R3 | 8 / 9 / 0 |
| Start | Enter |
| Select | Backspace |
Source: default bindings in the Play! source code (Source/ui_js/Main.cpp). Number keys are read from the top row, not the numeric keypad.
About Kingdom Hearts II (PS2)
Kingdom Hearts II is an action role-playing game for PlayStation 2, released in 2005 and developed by Square Enix together with Buena Vista Games. It is the second main installment of the Kingdom Hearts series and takes place one year after Kingdom Hearts: Chain of Memories. Sora, the hero of the earlier games, sets out again to find his missing friends while facing Organization XIII, a group of villains first introduced in Chain of Memories. As in previous entries, the cast mixes Disney characters and worlds with Square Enix properties.
Wikipedia says most of the first game's team returned, including director Tetsuya Nomura, and that they set out to address player feedback, offer more combat options and tell a deeper, more mature story. Critics reacted very positively and the game won several awards; reviewers praised its visuals, music, voice acting and emotional weight, though views on gameplay and story were mixed. An expanded Japan-only release, Kingdom Hearts II Final Mix, followed in March 2007.

How Kingdom Hearts II plays
You control Sora from a third-person camera and travel through interconnected field maps where battles happen. Story progress is linear, mostly delivered through cutscenes, and many side quests provide bonuses for characters. Experience points drive character growth: defeating enemies lets Sora and his allies level up and unlock abilities. Compared with the first game, the developers tried to fix complaints about the missing map and camera bugs.
Combat runs in real time with hack-and-slash attacks. A menu in the lower left corner, similar to the ones in Final Fantasy games, offers magic, items, summons and combined attacks with allies. A new feature is the Reaction Command, an enemy-specific move triggered by pressing the triangle button at the right moment; it can beat ordinary enemies, avoid damage and sometimes is required to finish a boss. Two computer-controlled party members usually fight alongside Sora, and the menu lets you tune their behavior somewhat.
The Drive Gauge has two uses: turning Sora into a Drive Form or calling a special character. In a Drive Form he bonds with party members, becomes stronger and gains new traits, and most forms let him wield two Keyblades. The gauge is not refilled at save points. Summoned Disney characters replace the two allies and now have their own menu. The Gummi Ship was reworked as a mix of rail shooter and theme-park ride: you fly it from above on the world map, and you unlock routes to worlds by clearing ship battles.

Kingdom Hearts II emulator FAQ
Is there a Kingdom Hearts II website to play online?
We are not aware of an official way to play Kingdom Hearts II online. What exists are browser-based PS2 emulators, such as Play!.js, that run a disc image of the game you own. We do not host or link to game files.
Do I need a PS2 BIOS to run Kingdom Hearts II?
Not with Play!. It emulates the PS2 system software at a high level, so no BIOS file is required.
Which version of Kingdom Hearts II works best in a browser emulator?
On the Play! tracker, the NTSC-U disc (SLUS-21005) and the Japanese Final Mix disc (SLPM-66675) are both Playable, while the PAL disc (SLES-54235) is In-game. The tracker covers Play! on all platforms, so browser results may be worse.
Do videos work properly in Kingdom Hearts II on Play!?
The tracker notes slow pre-rendered videos on all three tested discs: below full speed on the NTSC-U disc, much slower than gameplay on Final Mix, and very slow on the PAL disc. Real-time cutscenes and gameplay were reported fine on the Playable discs.
What is Kingdom Hearts II Final Mix?
It is an expanded re-release of the game with new and additional content, released only in Japan in March 2007. According to Wikipedia, a high-definition remaster later appeared worldwide inside the collection titled Kingdom Hearts HD 2.5 Remix.
Can I save my progress in Kingdom Hearts II in the browser?
In the browser version, saves are kept only in memory while the page is open, so they are lost when you close or reload it. Save points in the game also refill health and magic, but not the Drive Gauge.
Who made Kingdom Hearts II?
Square Enix developed and published it in collaboration with Buena Vista Games. Tetsuya Nomura directed, and most of the first game's team returned. It is the second main installment in the series and the third game overall.
